CONFIGURATION – BASIC LEVEL
Example B
– setting up:
•
a current input of 4 to 20 mA
•
displaying a range of 0 to 200psi
•
a fault detection level 10% above 200psi (engineering/display range) and 10% below 0psi (engineering/display range)
•
in the event of a fault being detected and/or the fault detection level being exceeded the process variable is driven downscale.

Basic Level – Analog Inputs
5.1.1
Analog Input Configuration Page
Information.
• Up to 12 analog inputs – on standard boards (inputs A1 to A6) and optional boards (inputs B1 to B3 or B1to B6).
• Universal inputs – mV, mA, V, THC, RTD and resistance.
• Internal cold junction compensation.
• Linearization – of temperature sensors or any electrical input to allow use of non-linearizing transmitters.
• Programmable fault levels and actions.
• Digital filter – to reduce the effect of noise on inputs.
Example A
– setting up:
•
a Type K thermocouple
•
measuring temperature in
F
•
displaying a range of 0 to 2000
F (e.g. Linearizer range 0 to 2000
F)
•
a fault detection level 10% above 2000
F (engineering/display range) and 10% below 0
F (engineering/display range)
•
in the event of a fault being detected and/or the fault detection level being exceeded the process variable is driven upscale.
